3 visuals for webpage
This code will help produce the three visuals that are going to be a
part of each equity tracker indicator webpage: regional map (tract
level) of most recent data, chart of the most recent data, chart of
trends over time.
If the indicator is a PUMS/OPSI indicator that can be accessed
through Elmer. Getting the data to a workable version may
require some data transformation. To explore, clean, transform, and
generate a final data set, please use the
data-gen-pums-template. This script will generate an .rda for
the map and an .rda for the charts. These data sets will be loaded in
before the data visualization code.
Indicator Explanation
[Please include the following for a general, layperson audience: 1-2
sentences explaining what your indicator is/measures, what it says about
people’s life outcomes; 1 sentence describing why it is useful/relevant
in the indicator’s theme]
1. Map of most recent data
To map data in this form, it requires accessing data at the
regional/tract level from ACS since the Elmer data set is already
aggregated to equity group/quintile.
